Parameters
pSrc
Pointer the source sparse keys vector.
srcStrideBytes
Distance in bytes between two consecutive elements of the source vector.
pDstIndx
Pointer to the destination vector of indexes.
len
Number of elements in the vectors.
pBuffer
Pointer to the work buffer for internal calculations. To compute the size of the buffer, use the SortRadixIndexGetBufferSize function.
Description
These functions indirectly sort all elements of the source sparse keys vector
pSrc
 in the ascending or descending order, respectively, using "radix sort" algorithm and store the indexes of resulting arrangement order in the destination vector
pDstIndx
. Elements of the source vector are not rearranged.
These functions require the work buffer for internal calculations, to compute the size of the required buffer, use the SortRadixIndexGetBufferSize function.
Intervals between the elements of the source sparse vector
pSrc
 in memory must be equal to the value of
srcStrideBytes
, minimum value of which is equal to the size of the data type of the key value. The sorting algorithm does not change the relative order of the elements with equal keys.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when the
pSrc
 or
pBuffer
 is
NULL
.
ippStsSizeErr
Indicates an error when
len
 is less than or equal to zero, or
srcStrideBytes
 is less than
sizeof
(
key type
)
.
